A selection of photos of the construction of my dome house, which I
believe is the first of this type in Maun

Rondavel walls are constructed up to 1.8m,
then a specialised plasticated canvas balloon is inflated in the structure
(see blue above) and a single-brick wall is layed over the balloon. The
balloon is continuously inflated by an air compressor during bricklaying,
but the compressor is turned off 2 hours after bricklaying each night, and
the balloon is re-inflated the next morning. The two domes are joined by a
1m long "tunnel."
